I only ride the flats here in south Florida, I don't race, maybe once a year I travel to Virginia to ride mountains so weight isn't an issue. I have Ultegra RD & FD so other than keeping the groupset the same is there any real reason to go Ultegra over the 105? What would you do?
I wanted to make sure that I actually responded to the OP, and didn't get too caught up in the ass-hattery that is brewing. Get the Ultegra. Will you immediately notice a decrease in weight, or vastly improved shifting? Maybe, maybe not. Who cares? Get what makes you happy.
